ind the general solution of the following linear systems. Sketch the phase portraits. Pick several points on the phase plane to plot the vector field and show your work. Plot also few trajectories. Please be neat in showing your solutions. Use Matlab to plot the vector field (on one figure) and to plot the solution to the system (on another figure). a)*?′+2?+3?=0 *?′ + 3? + 2? = 0 b)?′ =4?−12? ?′ = 5? + ? c) ?′ = −? + 3 ? ? =−6?−2? d)?′=5?−5? ?′ =5?−3?
